This meta-analysis aimed to update and evaluate evidence from randomized
controlled trials of tai chi for patients with chronic heart failure. METHOD:
Both English and Chinese databases were searched from their inception to June 2,
2016 (PubMed, EMBASE, Cochrane Central Register of Controlled Trials for English
publications and China Knowledge Resource Integrated, Wanfang, and Weipu
databases for Chinese publication). Titles, abstracts, and full-text articles
were screened against study inclusion criteria: randomized controlled trials
studying tai chi intervention for patients with chronic heart failure. The
meta-analysis was conducted with Revman 5.3 or STATA 12. RESULT: Thirteen
randomized controlled trials were included. Tai chi induced significant
improvement in 6-min walking distance (51.01 m; 30.49-71.53; P < 0.00). Moreover,
tai chi was beneficial for quality of life (-10.37 points; -14.43 to -6.32; P =
0.00), left ventricular ejection fraction (7.72%; 3.58-11.89; P = 0.003), and
B-type natriuretic peptide (-1.01; -1.82 to -0.19; P = 0.02). CONCLUSION: Despite
heterogeneity and risk of bias, this meta-analysis further confirms that tai chi
may be an effective cardiac rehabilitation method for patients with chronic heart
failure. Larger, well-designed randomized controlled trials are needed to exclude
the risk of bias.
